Question

4. The ratio of male and female teachers in a school is 5: 8. If there are 56 female teachers in the school. Find the total teachers in the school.

Answer 1

Answer:

91 teachers

Step-by-step explanation:

let the ratio be x

Now

8x=56

x=56÷8

x=7

Again

male teacher=5x

=5×7

=35

Total teacher=56+35

=91

Answer 2

Answer:

91 teachers in total

Step-by-step explanation:

Male : Female  

  5    :      8

Ratio can also be written if fractional form, therefore;

Let the number of males be = x

$\frac{Male}{Female} = \frac{5}{8} = \frac{x}{56}$

Remember equivalent fractions (whatever is multiplied to the denominator to get its pair is multiplied to the numerator to do the same)

Since 8 x 7 = 56, 5 x 7 will give 35

x = 35, there are 35 males

If you do not understand the equivalent fraction method, you can cross multiply to get the value of x

To get the total teachers in the school, add both the number of males and females = 56 + 35 = 91
